Active Fuel Tuning (MAP)

When trying to use "Active Fuel Tuning" (i.e. using MAP), I can't seem to download the changes the ECU is making into the calibration.

From a new calibration, these are the steps I've done:
Fuel > Uncheck "AFM Enabled", check "Use speed/density (map) fuel tables"
Fuel > Active Tuning > check "Active Fuel Tuning enabled"
Upload calibration to ECU.
Drive around for roughly 30 minutes.
Turn the car fully off.
Turn the ingition to the "ON" position.
Note: The second time I attempted this, I left the laptop on and flashpro plugged in.

Now here's where I get confused.

When I click "Download Active Tables from ECU" in either "Active Fuel Tuning Low" or "High" table, nothing gets updated. Everything (the Trim%) stays at 0.00. I've also tried "Merge active table into main tables" but there was also no difference in the adjustments.

What am I doing wrong?

Can someone list the proper way to use Active Fuel Tuning?

I've done Active AFM tuning (in Sensors > AFM > Active Fuel Tuning enabled) and after driving around for a short period of time, clicking "update Active Tuning Table" actually updated and changed flow values. I wanted to switch over to MAP and thought it would be as easy but it seems to be eluding me.

Thanks.

I updated my FlashPro manager to 2.8.7 and re-enabled fuel tuning from a new calibration (like the steps i did above).

I drove around for approx 40m and when i clicked the "download tables from ecu" button, it didn't update anything again.

Sorry for multiple replies but i always run out of time to edit the other posts, or i just don't see the edit button any longer.

I'm not sure if this will help, but this is the recent datalog from the drive i mentioned in the previous post.
also I'm including the calibration file I'm using.

When you're ready to upload the modified calibration to the ecu turn the key back one click(that turns the engine off but keeps all the computers up). Wait a few seconds then turn it forward one click but do not start the car. Now upload to ecu

That's not the issue I am having as I do know how to upload a calibration and have been trying to self tune my vehicle.

Re: Active Fuel Tuning (MAP)

I, too, have the same issue. I can't seem to download the ECU active table. I just get 0 everytime I download from ECU.

You have to save the calibration immediately after upload and then load the same calibration before downloading the changes.

just to summarize it..

So, in order to get this working do i have to... :

1- Upload the calibration
2- Save it again after uploading it, *do i have to store it in a different location?*
3- Go and ride with the car
4- Open the last saved cal and click on the download button from the active tuning table?
